Tensor Computing Interface: An Application-Oriented, Lightweight Interface for Portable High-Performance Tensor Network Applications
Rong-Yang Sun, Tomonori Shirakawa, Hidehiko Kohshiro +2
Tensor networks (TNs) are a central computational tool in quantum science and artificial intelligence. However, the lack of unified software interface across tensor-computing frame…
Closed-loop calculations of electronic structure on a quantum processor and a classical supercomputer at full scale
Tomonori Shirakawa, Javier Robledo-Moreno, Toshinari Itoko +18
Quantum computers must operate in concert with classical computers to deliver on the promise of quantum advantage for practical problems. To achieve that, it is important to unders…
Digital quantum simulation of many-body localization crossover in a disordered kicked Ising model
Tomoya Hayata, Kazuhiro Seki, Seiji Yunoki
Simulating nonequilibrium dynamics of quantum many-body systems is one of the most promising applications of quantum computers. However, a faithful digital quantum simulation of th…
Noise-stabilized discrete time crystals on digital quantum processors
Kazuya Shinjo, Kazuhiro Seki, Seiji Yunoki
Floquet many-body phases such as discrete time crystals (DTCs) are typically fragile to imperfections, and stabilizing them on noisy quantum hardware remains a central challenge in…
Low-energy photoexcitations inside the Mott gap in doped Hubbard and t-J ladders
Sumal Chandra, Kazuya Shinjo, Shigetoshi Sota +2
We investigate changes in the optical conductivity of doped Mott insulators by tuning ultrashort pump pulses to target either the Drude or low-energy absorption regions. Using a ho…
Pulse-based optimization of quantum many-body states with Rydberg atoms in optical tweezer arrays
Kazuma Nagao, Sergi Julià-Farré, Joseph Vovrosh +2
We explore a pulse-based variational quantum eigensolver (VQE) algorithm for Rydberg atoms in optical tweezer arrays and evaluate its performance on prototypical quantum spin model…
